Located high on a hill on the South Coast of England in the village of Clanfield (between Petersfield and Portsmouth) you will find a superbly equipped Observatory with a very active and enthusiastic membership.

We have a full program of Public Open evenings throughout the year at the Observatory coupled with monthly interesting and educational talks held at the ‘Clanfield Memorial Hall – Clanfield’ where you are more than welcome to attend.

Astronomy for Beginners Course

Astronomy is the oldest science and throughout the ages mankind has had a fascination for the night sky. This twenty-week course for adults over two terms, on Monday evenings from 7.15pm to 9.00pm at Clanfield Observatory, starting on Monday, 15th September 2014, is intended to introduce a basic understanding of astronomy with an emphasis on activities carried out by amateurs.

The course will include observations through some of the telescopes we have, when weather conditions permit.

As there is currently a surge of interest in astronomy, the course quickly fills up, so early enrolment is strongly recommended.
